A local truck is being offered for sale by auction. It's a 1990 Ford F-150 XL Supercab 4X2; has a 351W engine and a 4 speed E40D automatic transmission. It's low mileage and appears to be in very good condition. I don't need or particularly want a 4X4. I would only drive it when the roads are clear of ice and snow and the furthest it would ever get off road would be a camp site pull-through. I have been thinking of getting a small trailer - 16' or thereabouts. I know Ford has had problems with some of their engines (spark plugs that either self eject or won't come out at all). Is this one of those problem engines? Is this a generally reliable power train? Would this have any problems pulling a small trailer? And though mileage isn't a primary consideration, what sort of mileage could I expect?
